Answer:
x < 1/4
Step-by-step explanation:
Answer:
y = -1/2 x + 6
Step-by-step explanation:
2x + 4y = 24
4y = -2x + 24
divide each expression by 4
y = - 1/2x + 6
Answer:
30%
Step-by-step explanation:
Think of this as converting a fraction. 28/40 to x/100. You do this because in the situation, 40 is 100 percent of the price. So 28 is <em>x</em> percent of 100.
You multiply 40 by 2.5 to get to 100, so multiply 28 by the same number to get x. 28 * 2.5 = 70.
So 28 is 70 percent of 40. But the question is asking by what percentage it is <em>discounted. </em>If it's now selling for 70%, it has been discounted 30%. So the answer is 30%
The multiplier for a 7% increase is 1.07.
Time the price by the multiplier:
12.49 x 1.07 = $13.36
The symbol shown is a ray. A ray has an endpoint and includes all points on a line in only one direction. That is why the symbol above the letters XY has a single arrowhead. Ray XY starts at point X; it includes all points on line XY between X and Y, and also point Y and all points on the line past Y. It does not include any point past X going in the direction from Y to X.
